coating it with cement, carrying it to the tube and winding'it aroundthe same.

This invention further consists in the novel pneumatic mechanism forremoving a label from the bottom of a stack of labels in a box, andfeeding one end into the jaws of a carrying mechanism.

It' further consists of a novel mechanism for carrying the label fromthe pneumatic feeder to the applying mechanism, and for carrying a tubeto the proper vposition to receive the label.

It further consists in novel mechanism for applying therlabel to .thetube and for insuring the fastening down of the outer end.

The invention is' illustrated in the accompanying drawings, in whichFigure 1 is a general front view of the machine. Fig. 2 is a rear view,Fig. 3 is a plan. Fig. 4 is a front view with portions of the parts.broken away for the sake of clearness. Fig. 5 is a vertical crosssection on the line 5-5 of Fig. 1. Fig. 6 is a cross section on the line6-6 of Fig. 1. Fig. 7 is a plan of the two lower driving shafts. Fig.

8 is a detail of the label carrier.

Similar reference characters, refer to like parts throughout the severalviews.

The labeling machine here illustrated com-l prises a label holder; arotary device to eX- tract one label from the holder and feed one endo'f it to the gripping jaws of the label carrier, a coating device; atube carrier; means to wrap the label around the tube; means to ejectthe tube; and driving mech- :mism for the dierent parts.

The main driving shaft 10 is mounted in bearings secured to the lowerside of the bed l l of the machine, which bed is supported by logs 12,at any desired height. Each revolution of this shaft represents a cyclein the op` eration of the machine, and the pasting on'of one label.Mounted on this shaft are the gear wheel 7, the sprocket wheel 14 fordriving all the rotating parts above the bed, and the sprocket wheel 15for driving the coating mechanism. The gear 7 meshes with the pinion 4which is united to the pulley 9 and with it runs loose on the shaft 3. Asecond pulley 8 is independently loosely mounted on the shaft 3.

The coating mechanism/.nSecured to the lower' side of the bed is abracket 16. (See Fig. 4). A paste or glue receptacle 17 has a flange 18adapted to engage this bracket, and a second flange 24, through a slotin which the rod 19 extends. A collar 20 on this rod engages the flange24 and supports the same, while the upper end of the rod is screwthreaded into a hole in the bed. The rod may be turned by means of thewheel 21 and the height of the paste tank may be thereby adjusted.. Ascrew 22 in the bracket 23 holds the tank in position.

Extending down from the bed, beside the tank, (Fig. 6) are brackets 25which support the shaft 26 of the paste roller 27. On the end of thisshaft is a gear 23a which meshes with the gear 29a on the shaft 30a. Asprocket wheel 31a on `this shaft is driven by the sprocket wheel 15 bymeans of the chain 32a.

To insure an even coating of paste or glue on the roller 27, a blade 28is secured to the rodl 29 which is mounted in the walls of the tank 17.This blade hasy fingers 30 projecting over the ends of the rollerto'prevent ridges of dried glue forming thereon. An arm 31 on one endofthe rod 29 is provided with a screw threaded stud at its outer endwhich is engaged by the screw 32 mounted on the pin 33. The spring 34holds the head of the screw against the pin 33, and regulates thedistance between the blade 28 and the roller, and thus the thickness ofthe paste or glue on the roller will be controlled by the screw 32.

vThe Zabel holder and carrying mechanism-Mounted on the rear end of thebed is a supporting frame 34, provided with slots 35 and 36, and holes37. A plate 38 is secured to this frame by meansof bolt 39, and is heldin position by the pin 40 in one of the holes 37, which pin is engagedby a screw l41 mounted in the bracket 42 on the plate 38. A shaft 43 ismounted in this plate and in a bracket 44 projecting therefrom, and hassecured on one end the sprocket wheel 45 which is engaged by the drivingchain 46. .This

chain is ke t sufliciently tight bymeans of the roller 4 on the arm'48as shown in Figs. 2 and 3. Projecting from this plate 38 is a slottedcylinder 49 upon which is revoluble a drum 50 provided with holes 51.' Apipe 52 connects this cylinder with an air pump, so that a partialvacuum is maintained within this cylinder and drum, and a suction willoccur at those holes just above. the slot in the cylinder.

At the right end of the shaft 43.is a mutilated gear 53 Fig. 1 and astop plate 54. On the end of the drum 50 is a pinion 55 from which thepins 56 extend. This well known device is so adapted that the constantlyrevolvingshaft 43. will turn the drum 50 onel revolution -for one halfof the revolution of the shaft'43, permitting it to rest during theother half.

Mounted on the plate' 38 is a sleeve 60 in which is journaled a shaft 61carrying the label holder 62.. An arm 63 secured to this shaft engagesthe cam 64 on the lshaft 43.I A spring 65 holds the adjacent end of thelabel holder toward the drum 50.

The operation of these parts is as follows :-The shaft 43 running all ofthe time, the drum 50v will have equal periods of movements and rest.During the periods of rest, the low part of the cam 64 is in engagementwith the arm 63, and the label holder will be tipped down toward thedrum 50. The adjacent portion of the bottom of the label holder is cutaway (Fig. 4), permitting that endof the bottom label to lie on thedrum, where the label will be held through suction. Continued movementof the shaft`43l will cause the cam 64 to tip back the label holder andits contents, but the bottom label will be held down by the suctionthrough the holes 51. The drum 50 now begins to turn and feeds thisbottom label out of the holder. As each suction hole passes the slot inthe cylinder 49, its suction ceases, but that of another hole at oncebegins so that the labels will not be carried `around the drum, but befed forward in a practically straight line.

Mounted on the bed 11 are standard 66 and frame 67 which support theshaft 68 on which is mounted the drum to which are vformed the sprocketwheel 69, which carries the chain 46 to drive the mechanism just de.-scribed, and the sprocket wheel 70, which engages the chain 71 from thesprocket wheel 14 on the main shaft 10.

On the shaft 68 (Fig. 6) is secured a disk 73, and is slidable a seconddisk 74, engaged by the spring 75. )Vashers 76 preferably of leatherincrease the friction between these disks and the sprocket wheel drum,so that the chaink 71 which runs constantly, will turn "the shaft 68whenever it is released. The

double sprocket wheel 69--70 acts as a power transmission between theshaft y10 and the shaft 43.

Secured to the shaft 68 is the label carriel` having the two arms 7 7(Fig. 8) Aeach having Y lateral projections 72. A shaft 78 mounted inthe end of each arm carries a plate 7 9, adapted to swing out, as shownine'dotted lines, toadmit the end of the label. Fingers v projectingthrough holes in the plate 79,

prevent the labels going too far into the semicylindrical cup in the endof the arm. The projecting portions 72 on the arms 77 and the plates 79form the grippers of the label carriers. A double arm is secured to theend of the shaft 78 (Fig. 8), the upper arm 81 b eing engaged by thespring 82, to normally hold the plate 79 in gripping position, and fthesecond arm 83, being connected by the link 84 to a projecting lug on thecollar 85, which is mounted on the hub of the label carrier. (Fig. 6). Aroller 86 on the end of .arm 83. reduces friction with the cam 87 on theshaft 43.

lever having one arm 89 provided with a lateral extenslon adapted toproject into the path of the ends of the arms of the label carrier (Fig.4), while the other arm 90 (Fig. 2) engages the cam 91 on the shaft 43.A spring 92 (Fig. 3) holds this arm against the cam. The operation ofthese parts is as follows. The parts being. in the position shown inFigs. 1 and 4, the label carrier has justswung back andthe gear 53 isbeginning to turn the drum 50, and with it, to pull a label from theholder. As the label moves, it passes inv between the guide plates 93and 94 (Fig. 1) carried by the plate 38. Further turning of the shaft 43lcauses the high part of cam 87 .i

to engage the roller 86 on arm 83, forcing open the plate 79 so that theend of the label may enter the gripper. Further turning of the shaftwill cause the gripper to close and the high point on the cam 91 toengage the end of arm- 90, carrying'the end of the arm 89 from under theend of the carrier arm 77. At this point the high part of the cam 87 haspassed the roller 86 and the gripper has closed, locking the endA ofthe. label. The plate 38 has a notch 95 (Fig.,4) into which the lateralprojection on arm 89 may enter out of the path of 'the arm 77.

The-` friction between wheels 69-70 and disks 7 3--74 now swings thearms 77 around one half a revolution, the arm 89 immediately springsback into the path 'of the next arm 7 7 after the first is released. InVpassing the coating mechanism, the label is dragged over the cementcoated surface of the roller, the circumferential speed of the rollerbeing.

and is provided with pins 102 upon which the tubes are placedto receivethe labels. The disk turns the distance between pins 102 at each cycle,and presents a pin and tube opposite the label applying lmechanism ateach stopping of the arms 77. The tube carrier will be described furtheron.

Referring to Figs. 1, 3 and 5, the frame 67 is shown to extend tofurnish a bearing for the shaft 101. On this frame is supported a pin103, on which is pivoted a lever 104 carrying the roller 105 whichcontacts with the edge of the cam 106.A The end of the lever is.connected to the arm 107 through the link 108. This arm is secured tothe sleeve 109, mounted on the pin 110, secured to the frame 67. TheVarm 111 is also secured to this sleeve and carries the pipe 112 whichhas a connection to the air pump and has a row of holes as shown in Fig.3.

The pipe 112 lis shown in the path of the part 72 of the end of the arm77, but before the part 72 crosses the path of the pipe, the high partof the cam passes the roller 105, and the spring 113 pulls back the pipeout of the way. mmediately after the arm 77 has passed, the pipe swingsback in time to contact withthe lower end of the label hanging down fromthe gripper, and as the suction is on, will hold the label 'with someper sistence, causing it to be stretched .fiat and straight when inwrapping position.

The pulleys 8 and 9, and the pinion 4 are loose on the shaft v3. Thegear 115 and disk 116 are joined by the sleeve 118 loose on the shaft 3.The gear 115 is intermittently driven by the mutilated gear 128, theperiods of rest being fixed by the disk 117 and pins 127. The disk 116is -provided with a slot in which is adjustably secured a pin 1197 (SeeFigs. 1 and 3) onwhich is pivoted one end of the rod 120. A rack 121 isslidable in a sleeve 122, mounted on the shaft 123, which rack is inengagement with the gear 124. A turn-buckle adjusts the position of therack.

The shaft 123 also carries the gearv1v25 (Fig. 6) which engages the rackteeth cut in the longitudinally movable cylinder 126. Slidably mountediii this cylinder (Fig. 4) is a rod 127, having a reduced end 128 uponwhich is mountedaA spring'129. A collar 130 on the rod 128 limits themovement of the rod with respect to the cylinder. The spring engages theflange 131 of the cylinder and the enlarged portion 127 of the rod.

On the outer end of the rod 127 is a plate 132 which carries a buffer133 of rubber or other desirable material. A collar 134 is se cured tothe end of the cylinder 126, and on the pins 135 on this collar arepivoted the arms 136 which carry rollers 137 at their outer ends. Thearms 136 areJ crossed at one side of the collar as shown in Fig. "2,

and their free-ends connected by the spring 138 which holds the rollerstoward each other.

The operation of the label applying mechanism is as follows. rThe partsbeing in the position shown in solid lines in Fig, 4, and the shaft 3with disk 116' turning tothe right, the rack 121 Will move down, turningthe vshaft 123 and gear 125 to the right. This will move the rollers 137and the buffer 133 outward, the buer pressing the label against the tubeas shown in Fig. 1. Here the` buffer Will remain, but the rollers willcontinue, passing over the top and bottom of the tube as shown in dottedlines in Fig 4. At the time that the buer contacts with the label, thecam 87 has passed the roller 86 on the arm 83 toward the shaft 68 toopen A l porting thel label adjacent the tube, releas ing the labelwhich is then rolled against the ,tube by the rollers, 137. Continuedmovement of t-he shaft 3 causes the parts to return to normal position.t

` As the rollers 137 are moving back, a

shaft 151.

Referring to Figs. 1. 3 and 5. it will be seen that the frame 67 has aninwardly projecting arm 140 provided with a bearing for the inner endsof the shafts 101 and 141. The crank arm 142 secured tothe outer end ofthe shaft 141 has a link 143 pivoted to it, whose lower end is forkedand fits over the shaft 10. The disk cam 106 has a slot 145 in which thepin 146 on the link 143 travels, and this cam will cause the shaft 141to rock. lThe sleeve147 on the shaft 141 .has

yan arm '148, mounted in the forkedend of which is a shaft 149! A pairof arms 150 support a roller 151. One arm 150 carries a plate 152adapted to engage the brace or guide 153 projecting from the frame 67. Aspring 154 on the shaft 149 tends to force the roller 151 outward. Theaction of these parts is as follows. While the rollers 137 a re movingback out of the Way, the link 143 descends. carrying down the arm 148.The plate 152 sliding down the guide 153 cames to the corner, permittingthe spring 154 to throw out the roller 150 which will be drawn downtheright side (Fig. 1) of the tube, as shown in dotted lines. Furtherturning of the shaft 10 will swing the parts back to position.

Through mechanism to be explained, the

.tube which has been previously labeled has ,mechanism is brought intoplay to turn y`down the projecting upper end of the label against theside of the tube facing thev means of the spring 157.

It should be held down while the lower end is being brought up.

Pivoted on the pin `155 projectinginward from the frame 67 is a bellcrank lever 158 carrying the roller 156. y (Fig. l). This roller is heldin the path of 'the tubes by As the tube passes this roller, the lowerend of the label will be swept up over the tube and pasted down. To tuckthe upper end of the label under the lower end, a pin 160 (Fig. 1) ispivoted inthe arm 148, and adjustably mounted on this pin is a rod 161..A crank arm 163 1s mounted' on the frame 67 and in its end is A platelower end, just before it is pressed downl by the roller 156. v,Seedotted lines in Fig. 1. The tube ca'rrz'er.l\4ounted on the bed 11 arethe frames170 and 67, which latter has a bracket 140. Av shaft 101 ismounted in the bearings of the frames 'and has secured to it the disk172, has slidably mounted on it the disk 173 and has secured to it thetube carrying plate 100. A spring 174 between the disk 173 and the hubof the tube carrier presses washers 175, preferably of leather,againstthe sides of the sprocket wheel`17 6. This sprocket wheel carriesa chain 71 which is constantly driven by the sprocket wheel 14 on theshaft 10. The friction between Ithe sprocket wheel 176 and the washersand disks is such that the tube carrier will turn whenever released. l

'Mounted on the bed l1 is a bearing 178 for the pin 17 9 which carriesthe bell crank lever 180. 'A spring 181 (Fig. 4) normally holds theupper arm of the bell crank against the edge of the plate 100. The lowerarm car ries a roller 182 which engages the cam 183 on the shaft 10. Thehigh point of this cam will swingihe lupper arm of the bell crank out ofthe notch 184 in the plate 100-'immediately after a label has beenapplied to a tube, and the arm will spring up in time to engage in thenext notch.

The plate 185 is a segment supported by arms 186 secured to the bracket.140. 'The outer edge of the plate extends to the tube `carrying pins102 and limits the distance the tubes may be slipped onto the pins. Thetubes are placed on these pins by hand.

The tube @jeden-Secured to the' shaft 10 (Figs. 5 and 7) is a drum cam190 adapted to engage a 'pin 191 on the arm 192 of the sector 193 toswing the same to the left. The spring 194 returns the sector. The arm192 is mounted on the pin 195 secured to the bed 11. A shaft 1-96 isjournaled in the bed and has a gear 1,97 at its lower endand a secondgear 198 at its upper end. (Fig. 3).

` Mounted in the guide sleevefr 199 on the bed, is a rack 200 engaged bythe gear 198. On the outer end of the4 rack is a plate 201 which willscrape along the tube carrier pins those pins 102 which are adjacent tothe,

segment 185, the distance they are slipped on being limited by thisplate. The operator also keeps the label holder 62 and the glue tank 17supplied.

In operation, the drum 50 feeds a label into the gripper, the plate 201begins to push oli' a finished tube and the bu'er 133 moves up to hold alabel against a tube. Next the grippers open simultaneously, one toadmitthe end of a label and the other to`release a label so it may beattached to a tube. The rollers 137 also move out over the upper andlower sides of the tube, and the suction pipe 112 begins to swing awayfrom the path of the grippers. Next the grippers close, one empty, theother onto a label, the rollers 137 move back, and the `cam 106 causesthe roller 151 to move down to turn down the upper end of the Ylabelthat has just been applied. At the same time the plate 162 tucks in thepossible loose end of the label under the lower end just being turned upby the roller 156. The ejector is also returned to normal position byits spring an'd the caml 91 completes the withdrawal of the arm 89 fromunder the end of the arm 77, and the lever 180 releases the tube carrier100.

The arms 77 swing around through one half a revolution, a label beingdragged over the roller 27. The carrier plate moves to bring anothertube opposite the buffer. At

the same time, a tube is moved undeuthe into the path of the grippers intime to engage the label sufficiently long to straighten it, while theroller 151 and plate 162 return to normal position. The machine hascompleted one cycle, and the time consumed is about one second. It willbe observed that t-hisI machine is not limited to the applica-v materialfor this machine.l For certain- .tubes, the buffer 133 may be omitted.
